    How Was It invented?How Does It Work?So What's The Catch?The technology was actually invented pretty much by accident, by Luigi Cassar, an Italian chemist at cement manufacturer Italcementi. He was trying to create a construction material which would keep a bright white colour even in polluted conditions, and hit upon a method called "photocatalysis", which uses the sun's energy to zap away dirt. To his surprise, when the air aroundthe treated concrete was tested, it contained up to 80 per See more on citymetric
